No A/C Low Pressure Port | Altima 2005

[James Gunter]

I have a Nissan Altima 2005 V6 SE, manufacture date November 2004. I have spent the past month searching for the low-pressure port in my A/C system, and I cannot find it. It isn’t near the high-pressure port, as with every other 2005 V6 Altima I find. Auto parts stores can’t find it, online forums and YouTube can’t find it, and even my local dealership can’t give me the information I need. Can anyone help?

I should add that I am a mechanic myself and am certified to operate on A/C systems. This one is just throwing me for a loop. Sheesh.

Here is the FSM section for the 2005 Altima, The refrigerant line diagram shows both a high and low side service port.
